Last updated
Quick answer: To convert RM to AVI, add the RM file to the iHateFiles RM to AVI converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. RM is a format most software has stopped opening. AVI is not.
Should you convert RM to AVI?
Yes. RM is a format most current software no longer opens, so converting it is the reliable way to keep watching it. AVI is a reasonable target; MP4 is the safest.
The picture is re-encoded
An RM usually holds RealVideo with RealAudio sound. This writes MPEG-4 Part 2 (Xvid) video with MP3 sound into the AVI. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from RM artefacts rather than the original.
Where the AVI will play
AVI plays on Windows Media Player, VLC and old DVD players with DivX support.

| Inside the file | RealVideo with RealAudio sound | MPEG-4 Part 2 (Xvid) video with MP3 sound |
| Compression | Lossy | Lossy |

| Here | Read only | Read and write |
What usually goes wrong
About the RM. The quality ceiling was set when the file was made, on a dial-up budget. Converting preserves it rather than improving it.
About the AVI. Audio drifting out of sync partway through an AVI is common, because the container assumes a fixed frame rate that the source did not actually have. Re-encoding to MP4 corrects the timing.
How to convert RM to AVI
- Add your RM file. It is read from your disk and stays there.
- Check the settings. The output format is already set to AVI.
- Press convert and the AVI file is saved back to your device.
Questions
How do I convert RM to AVI?
Open this page, add your RM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this RM to AVI converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to AVI lose quality?
AVI is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several RM files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
